The Thioredoxin Encoded by the Rod-Derived Cone Viability Factor Gene Protects Cone Photoreceptors Against Oxidative Stress [PDF]

open access: yesAntioxidants & Redox Signaling, 2016
Rod-derived cone viability factor long (RdCVFL) is an enzymatically active thioredoxin encoded by the nucleoredoxin-like-1 (Nxnl1) gene. The second product of the gene, RdCVF, made by alternative splicing is a novel trophic factor secreted by rods that protects cones in rodent models of retinitis pigmentosa, the most prevalent inherited retinal disease.

Numerical Simulation Analysis of Influences of Microgroove Texture on Friction Performance of Expansion Cone

open access: yesShiyou jixie, 2023
The current evaluation of expandable tubulars focuses on the expansion quality and neglects the friction performance of the expansion cone.Given this,the elastoplastic theoretical derivation is performed to calculate the counteractive surface pressure ...

A new energy-absorbing bolt used for large deformation control of tunnel surrounding rock

open access: yesInternational Journal of Mining Science and Technology, 2022
In order to control the large deformation of tunnel surrounding rock, a new energy-absorbing bolt is developed. This bolt can be transformed into a rigid support when the deformation of the surrounding rock reaches the length of the sleeve tube, thus ...

Free Surface Effects on Normal Stress Measurements in Cone and Plate Flow

open access: yesApplied Rheology, 2007
The effects of free surface shape on normal stress difference measurements in cone and plate flow are investigated. The analysis shows that the stress field is significantly altered by deviations of the free surface from an ideal (spherical) shape.

Light-cone fluctuations and the renormalized stress tensor of a massless scalar field

open access: yes, 2012
We investigate the effects of light-cone fluctuations over the renormalized vacuum expectation value of the stress-energy tensor of a real massless minimally coupled scalar field defined in a ($d+1$)-dimensional flat space-time with topology ${\cal R ...
